Our recommendations: If you intend to transport an instrument of a tuba's size and value on any regular basis, you need a protective case. Besides the usual wood cases, there are also hard shell synthetic cases and gig bags. You should take care to achieve maximum protection at minimum weight and size. Don't think of it as an unnecessary extra expense, but as a protection of the investment in your instrument and as an insurance policy. Think of the space your car affords, and think of your actual transport needs. If your instrument often accompanies you on a tour bus, for example, you'll be needing better protection than if all you do is drive your instrument between your home and your rehearsal room.
Our recommendations: Considering the tuba's not insignificant weight, players are grateful for every bit of support. There are tuba stands that allow you to safely set down your tuba, there are stands on which you can play your tuba with great comfort, and there are carrying aids and straps which improve your instrument's weight distribution.
Our recommendations: Unfortunately, you can't always enjoy your tuba's wonderful sound at full volume. A practice damper allows you to practice in your home or your hotel room without worrying about bothering your neighbours.
Our recommendations: Such a valuable instrument deserves to be taken care of properly. Varnish care, valve oil, cleaning cloths, cleaning rods... there's so much to do!
